Floating point vs Fixed point 1. basic: reference: http://blog.leanote.com/post/google-w3dian0/%E5%AE%9A%E7%82%B9%E6%95%B0 http://www.cnblogs.com/cloudseawang/archive/2007/02/06/641652.html 数值数据,分为整数和实数。在计算机中,整数用定点数表示,实数用浮点数表示。 定点数 计算机中采用...
One important feature that distinguishes different processors is whether their CPUs perform fixed-point or floating-point arithmetic. In a fixed-point processor, numbers are represented and manipulated in integer format. In a floating-point processor, in addition to integer arithmetic, floating-point ...
It is inefficient to perform floating-point arithmetic on fixed-point processors , Since all the operations involved, must be done in software. 12 Digital Signal Processing - Floating point processors usages Floating point processors usages In military radar, the floating point processor is frequently...
The two major methods by which a digital signal processing (DSP) system can be implemented in LabVIEW in order to match to its hardware implementation on a processor include fixed point and floating point method. In a fixed-point processor, numbers are represented and manipulated in integer ...
The plot shows that the fixed-point results do not closely match the floating-point results. Increase the word length to24and then convert to fixed point again. fxptcfg.DefaultWordLength = 24; fiaccel-args{complex(0, 0)}-float2fixedfxptcfgmyFilter ...
point number, which is not clear in any of the documentation - Documentation section '9.1.2. Numbers' should indicate which numbers are fixed point, and which numbers are floating point. Alternatively, may I submit a patch that correctly treats 0.123456789012345678900123456789E20 as a fixed point ...

Changing the default data width(32 bits) in Altera floating point ip cores vs Using fixed point ip. Are these two things not the same? If I can reduce the data width of a Altera floating point ip to something of my choice then will it not be the same and as good...
The U.S. dollar is a floating currency, much like most of the major currencies in the world. The value of the dollar floats with its demand in the global currency markets. At one point, the U.S. dollar was a fixed currency with its peg to the value of gold. ...
The utilitiy Float2Qpt allow the user to convert floating point numbers to either signed or unsigned fixed point numbers in a Q(QI.QF) format with automatically selected or user definable word lengths, and automatically selected or user definable error tolerances (epsilon). Alternatively a user ...
